1.源码下载
git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
cd ijkplayer-ios
git checkout -B latest k0.8.8
接着是./init-ios.sh，
这一步很慢，主要是要从github上下载ffmpeg等依赖，所以把init-ios.sh文件改一下，把github的源替换成gitee的，如下所示：
# IJK_FFMPEG_UPSTREAM=https://github.com/Bilibili/FFmpeg.git
IJK_FFMPEG_UPSTREAM=https://gitee.com/yuazhen/FFmpeg.git
# IJK_FFMPEG_FORK=https://github.com/Bilibili/FFmpeg.git
IJK_FFMPEG_FORK=https://gitee.com/yuazhen/FFmpeg.git
# IJK_GASP_UPSTREAM=https://github.com/Bilibili/gas-preprocessor.git
IJK_GASP_UPSTREAM=https://gitee.com/yuazhen/gas-preprocessor.git
#FF_ALL_ARCHS_IOS8_SDK="armv7 arm64 i386 x86_64"
FF_ALL_ARCHS_IOS8_SDK="arm64 x86_64"#移除32位支持，i386 x86_64是模拟器的
然后执行./init-ios.sh
2.解码器配置
$ cd config
module-default.sh 更多的编解码器/格式
module-lite-hevc.sh 较少的编解码器/格式(包括hevc)
module-lite.sh 较少的编解码器/格式(默认情况)
添加rtsp解码支持
编辑module-lite.sh文件，添加下面2个配置
export·COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS·--enable-protocol=rtp"
export·COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS·--enable-demuxer=rtsp"
删除当前的module.sh 文件
rm module.sh
创建软链接 module.sh 指向 module-lite.sh
ln -s module-lite.sh module.sh
3.添加 https 支持
最后会生成支持 https 的静态文件 libcrypto.a 和 libssl.a, 如果不需要可以跳过这一步
获取 openssl 并初始化,也要先替换成gitee源，pull_fork只保留arm64和x86_64
./init-ios-openssl.sh
在模块文件中添加一行配置 以启用 openssl 组件
echo 'export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-openssl"' >> ../config/module.sh
添加完后重新生成软链接
删除当前的module.sh 文件
rm module.sh
创建软链接 module.sh 指向 module-lite.sh
ln -s module-lite.sh module.sh
4.编译
cd ios
编辑 compile-openssl.sh compile-ffmpeg.sh，移除32位支持
FF_ALL_ARCHS_IOS8_SDK="armv7 arm64 i386 x86_64" 改为
FF_ALL_ARCHS_IOS8_SDK="arm64 x86_64"
编译openssl, 如果不需要https可以跳过这一步
./compile-openssl.sh clean
./compile-openssl.sh all
编译ffmpeg
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
5.合并动态库
如果使用 https, 那么需要手动给IJKMediaFramework添加 libcrypto.a 和 libssl.a 文件, 默认不会添加
ps: 这两个依赖库的目录为ijkplayer-ios/ios/build/universal/lib, 只有进行了上面跟 openssl 相关的操作, 才会在这个目录下有生成libcrypto.a 和libssl.a
大家会发现除了
IJKMediaFramework这个target, 还有一个叫IJKMediaFrameworkWithSSL, 但是不推荐使用这个, 因为大部分基于ijkplayer的第三方框架都是使用的前者, 你把后者导入项目还是会报找不到包的错误, 就算你要支持https也推荐使用前者, 然后按照上一步添加openssl即可支持
打开ios/IJKMediaPlayer并运行，分别真机和模拟器编译，生成动态库
合并IJKMediaFramework
lipo -create 真机framework路径 模拟器framework路径 -output 合并的文件路径
lipo -create Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework -output IJKMediaFramework
直接替换掉Release-iphoneos中的IJKMediaFramework就行
6.测试
新建工程并导入IJKMediaFramework.framework 添加libc++ libz.tbd libbz2.tbd3个支持文件
测试地址可以用live555MediaServer文件把本地视频映射成rtsp协议的视频。执行./live555MediaServer，按提示操作就行
import UIKit
class playerViewController: UIViewController {
var iPlayer:IJKFFMoviePlayerController?
override func viewDidLoad() {
super.viewDidLoad()
let options:IJKFFOptions = IJKFFOptions.byDefault()
let url:URL = URL.init(string: "rtmp://live.hkstv.hk.lxdns.com/live/hks")!
self.iPlayer = IJKFFMoviePlayerController.init(contentURL: url, with: options)
var arm1 = UIViewAutoresizing.init(rawValue: 0)
arm1.insert(UIViewAutoresizing.flexibleWidth)
arm1.insert(UIViewAutoresizing.flexibleHeight)
self.iPlayer?.view.autoresizingMask = arm1
self.iPlayer?.view.backgroundColor = UIColor.white
self.iPlayer?.view.frame = CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: 300)
self.iPlayer?.scalingMode = .aspectFit
self.iPlayer?.shouldAutoplay = true
self.view.autoresizesSubviews = true
self.view.addSubview((self.iPlayer?.view)!)
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.iPlayer?.prepareToPlay() //准备
self.iPlayer?.play() //播放
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
self.iPlayer?.pause()//暂停
// self.iPlayer?.shutdown() //销毁
}
}
7.遇到的问题&解决办法
1.第一次加载播放器时卡主线程
直接修改IJKMediaPlayer中IJKSDLGLView.m的源码
可以在github直接下载修改好的源码文件
首先，增加个只在主线程操作的方法，这个方法里面就是先判断当前是否在主线程，如果是就直接执行，否则同步切换到主队列进行执行。
static void IJKHanleInMainThread(dispatch_block_t mainThreadblock) {
if ([NSThread currentThread] == [NSThread mainThread]){
mainThreadblock();
} else {
dispatch_sync(dispatch_get_main_queue(), ^{
mainThreadblock();
});
}
}
其次将方法- (BOOL)isApplicationActive里面改成这样：
__block UIApplicationState appState = 0;
IJKHanleInMainThread(^{
appState = [UIApplication sharedApplication].applicationState;
});
将方法- (void)displayInternal: (SDL_VoutOverlay *) overlay里面改成这样
IJKHanleInMainThread(^{
[[self eaglLayer] setContentsScale:_scaleFactor];
});
IJKHanleInMainThread(^{
[_context renderbufferStorage:GL_RENDERBUFFER fromDrawable:(CAEAGLLayer*)self.layer];
});
最后执行IJKMediaPlayer的demo，发现子线程操作UI的那些警告就没有了。这样重新编译生成动态库
或者直接下载poholo/ijkplayer里面的IJKSDLGLView.m文件
2.当视频地址相同，只有端口不同时，视频重复
修改源码，使用url+端口判断是否同一个链接
修改如下3个文件源码，修改后，其他架构的可以直接替换
可以在github下载修改好的直接替换
